List your requirements
Write down the markets you need, the devices you use, the number of saved layouts and alerts you expect, and whether you need exports. Separate essential features from optional extras.
Check coverage and cost
Confirm which exchanges are included, whether quotes are delayed, and which data feeds cost extra. Add the subscription, data fees, taxes, and any required upgrades to your comparison. Check trial renewal and cancellation terms before subscribing.
Run the same small test
On each platform, find the same symbol, switch timeframes, save a layout, create an alert, and export an image. Try those tasks on the device you will actually use. Record any limits or steps that slow you down.
Check what you can take with you
Look for ways to export watchlists, notes, and images. Find the help documentation and check which features remain available if you cancel or downgrade. Save the comparison so you can revisit it before renewal.
